Sir Terry Matthews
Rank 2017
Matthews will always be lauded as the man who brought the Ryder Cup to Wales. His Celtic Manor Resort hosted the iconic contest in 2010, when Europe narrowly beat the US, after the Canada-based entrepreneur invested more than £150m to create one of Europe’s leading golf resorts.
   Despite amassing his wealth on the other side of the Atlantic, Newport-born Matthews, 73, remains a passionate campaigner for Welsh interests. He has pushed for the Swansea Bay tidal lagoon, the electrification of the rail line between Cardiff and Swansea, and became involved in a proposed rescue deal for the Port Talbot steelworks.
   After obtaining an electronics degree at Swansea University he went to Canada and made his fortune, first with a telecoms company called Mitel that was sold to BT. However, the bigger earner was Newbridge Networks, which Matthews sold to Alcatel in 2000 for £4.4bn, collecting £1bn for his stake. Today he floats between Canada and Wales. He is the founder and main investor in Celtic House, a venture capital group investing in hi-tech start-ups. His Wesley Clover Corporation owns Celtic Manor, showing profits of £4m and assets of £52.2m in 2015. He also owns the Brookstreet hotel and golf resort in Ottawa.
